COTTON-SEED HULLER.

To all whom it may concern:

Be it known that I, HARDY L. OATHEY, citizen of the United States,residing at Erick, in the county of Greer, Oklahoma, have inventedcertain new and useful Improvements in Cotton-Seed Hullers, of which thefollow ing is a specification.

This invention has for its object a simple durable and efficientconstruction of cotton hulling machine, designed to prepare the seedcotton to enter the gin free from burs, dirt, sticks and other foreignsubstance, thereby greatly prolonging the life of the gin proper andproducing other advantageous results hereinafter specifically set forth.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a side elevation of my improved cotton hulling machine. Fig.2 is a top plan view thereof. Fig. 3 is a longitudinal sectional view.Fig. 4 is a detail perspective View of the feed plate.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral 1 designates the casing of myimproved cotton hulling machine, said casing being separated from thebreast 2 by means of the inclined slotted board 3 producing a series ofribs 3 Saws 4 are mounted on the shaft 5 in the framework 6 so as toproject through the spaces between the several ribs 3" into the 'the topof the breast.

breast.

A feed bed 7 is mounted on a rod 8 in slotted bearings 9 in the breast,so that the said feed bed may be tilted to different inclinations orraised up and down to suit the requirements of feeding.

10 designates an apron which is provided with a series of transverseslats 11 and which is mounted on the transversely extending rollers 12and 13 journaled in bearings 14 at The apron 10 is inclined, as shown,and extends into close proximity with the inclined board 3 at the upperends of the ribs 3, with its lower stretch running in a straight linefrom the ribs for a purpose hereinafter described in connection with thedescription of the operation of the machine. The roller 13 of theSpecification of Letters Patent.

to receive the seed cotton and carry it out to the gin proper, throughsuitable feeding means (not shown).

The drive shaft 20 of the machine is provided with a belt wheel 21 whichextends around an idler 22 and thence over a pulley 23 on the shaft 24of the shaft cleaning drum 18. Said belt also extends around the pulley25 on the end of the shaft 5 so as to revolve the saws.

In the practical operation the machine receives the cotton, burs,seedand lint together and separates the seed and lint from the hulls orburs, the latter going out in front of the machine, and the seed andlint being caught by the saws and carried to the ribs and thencedisengaged from the ribs and dropped in the suction fine and thencecarried to the gin proper. The cotton, in the hulls or burs, just as itcomes from the stalks, is fed over the breast against the adjustablefeed bed 7, and moves upon the same into contact with the saws, theteeth of which are so formed as to readily take hold of the cotton andfree it from the hulls, but in such a manner as to not cut or break thefibers or release the lint from the seed. As soon as the cotton comes incontact with the saws, it is carried to the inclined ribs 3 where itmeets the reverse motion of the endless apron 10, which is revolved veryrapidly and so agitates the cotton as to form a complete but fiuffy rollwithout the necessity of forcing a roll by heavy feeding which wouldincrease the density of the roll, this being a very advantageous featureof my machine. Furthermore, it will be noted that the apron 10, by itsmotion prevents the machine from packing or choking and this is the mainseparating element of the machine, as all burs, stalks, and otherforeign matter, are thrown back over the cottonin the roll and fall outin front, as the front of the breast 2 is entirely open and unobstructedbetween the apron and feed bed thereby leaving the seed cotton fiuffyand in proper condition to enter the gin proper. The apron 10 keeps thecotton in motion in the breast of the huller until tion with theaccompanying drawing, it will be seen that I have provided a cottonhulling machine which is simple in construction and not liable to getout of order and which is an efficient agitator and separator of theburs and dirt, stalks and the like from the seed cotton, preparatory tofeeding the seed cotton into the gin.

Having thus described the invention, what is claimed as new is:

1-. A cotton hulling machine, comprising a casing, a breast, a series ofribs separating the casing from the breast, a feed bed mounted in thebreast, a series of saws mounted in the casing and projecting throughthe spaces be tween the ribs into the breast, an inclined endless apronmounted in the breast with its lower stretch running in a straight lineaway from the ribs, means for imparting a traveling movement to theapron, and means for driving the saws, the entrance opening or front ofthe breast being unobstructed between the apron and feed bed.

2. A cotton hulling machine, comprising a casing, a breast, a series ofribs separating the casing from the breast, a feed bed mounted in thebreast, a series of saws mounted in the casing projecting through thespaces between the ribs into the breast, means for driving said saws, aninclined endless apron mounted in the breast with one roller located inclose roXimity to the saws and ribs, and with its ower stretch runningin a straight line away from the said ribs and saws, said a ronembodying a series of transverse s its, and

means for imparting movement to'the apron,

the entrance opening or front of the breast being unobstructed betweenthe apron and feed bed.

3. A cotton hulling machine, comprising a casing, a breast, a series ofribs separating the casing from the breast, a series of saws mounted inthe casing and projecting through the spaces between the ribs into thebreast, means for driving the saws, an inclined endless apron mounted inthe breast with its lower stretch running in a straight line away fromthe ribs, means for imparting a traveling movement to the apron, andafeed bed mounted in the breast and forming with the lower stretch ofthe apron an entrance opening for the front of the breast which isentirely unobstructed from the saws outwardly between the bed and apron,the apron being outwardly diverging with respect to the bed as a whole.

4. A cotton hulling machine, comprising a casing, a breast, a series ofribs separating the casing from the breast, a series of saws mounted inthe casing and projecting through the spaces between the ribs into thebreast, means for driving the saws, a feed bed mounted in the breast, aninclined endless apron mounted in the breast above the feed bed andembodying a series of transverse slats, the lower stretch of the apronrunning in a straight line away from theribs and the apron divergingoutwardly from the bed as a whole, the s ace between the bed and apronbeing entire y unobstructed or unrestricted, and means for imparting atraveling movement to the apron.

In testimony whereof I afliX my signature in presence of two witnesses.
